Silencer bracket dimensions

I cant see any reason it would be different to the dominator bracket. Usually if the silencer does not fit its most likely that its a a poor silencer copy.  or even a too short pipe. The three silencers I have for Dommys all needed denting to miss the frame where the mounting points were missplaced.I will look for my spare bracket to measure it.

Nope, I am wrong !,  Singles have a different part number, 21121.

The silencer bracket for a 1962 Model 50 and ES2 is part number 22097 which the NOC Spares Scheme has in stock.
